Abstract
Official abstract text for this publication.
A combustion assembly for a gas turbine includes a flame tube and a fuel supply including a flow rate limiter supplying an injector. The flow rate limiter and the fuel injector are formed in one piece.
First claim
Opening claim text (preview).
1 . A combustion assembly for a gas turbine comprising a flame tube and a fuel supply including a flow rate limiter supplying an injector, wherein the flow rate limiter and the fuel injector are formed in one piece, and wherein the flow rate limiter comprises a first fuel conduit and a second fuel conduit each comprising a succession of chambers which are interconnected by reduced section portions, the first conduit and the second conduit being connected to a fuel inlet, the first conduit opening downstream into a first channel of the fuel injector and the second conduit opening downstream into a second channel of the injector. 2 . The assembly according to claim 1 , wherein the fuel injector has a substantially L-shape, a first branch of which includes the first channel including an upstream end which is connected to the first conduit of the flow rate limiter and a downstream end which opens into a first fuel outlet end piece, and a second branch of which includes a second fuel outlet end piece which is connected to a downstream end of the second channel which extends in the first branch and in the second branch. 3 . The assembly according to claim 1 , wherein at least one air inlet is formed at the junction of the injector and the flow rate limiter. 4 . A turbomachine comprising an assembly according to claim 1 . 5 . A method for manufacturing an assembly according to claim 1 , comprising the step of making the flow rate limiter and the fuel injector by additive manufacturing. 6 . The method according to claim 5 , wherein the additive manufacturing is of the laser powder fusion type.
